“Jackets and Their Insignia
Multicolored jackets are available for optional wear by youth members and adult leaders. The universal emblem should be worn on the left
pocket or, in case of a jacket without chest pockets, in the same area. The Philmont bull emblem is especially designed for the red wool jac-shirt to be sewn on the left side above the pocket.
On all jackets, Philmont Scout Ranch, Philmont Training Center, or high-adventure base emblems may be worn centered on the right pocket or in the same relative position if there is no pocket. The Order of the Arrow has adopted the jac-shirt as its official jacket, and members may wear the 6-inch national Order of the Arrow patch centered on the back.
The large Philmont, NESA, jamboree, National Camping School, and international participant emblems are approved to be worn on the back of the jacket. Only one such emblem may be worn at a time.”
